To all whom t may cofrtcemf'.'

Be it known that l, WILLIAM H. Hass, a citizen of the United States,residing` at 5824 'Harper AAvenue, Chicago, in the county of' Cookv andState of Illinois have invented a new and useful improvement inGratings,

of which the following is a specification.

My invention relates more particularly, though Vnot exclusively, to,improvements 1n registers formed as a part of hot air furnaceinstallations, and more especially to registers which are located infloors, and wherein it is desired that the upper surfaces of the variousportions of the register extend in the same plane; and my primary objectis to provide a novel, simple and eco-,

nomical construction lof grating, the parts of which may be quicklyassembled to form vthe finished structure, and which will be durableland serve its purpose in a satisfactory manner.

Referring to the accompanying drawlng:

Figure 1 is a plan view of a register constructed in accordance with myinvention, Figure 2 is an enlarged, broken section taken at the line 2-2on Fig. 1 and viewed in the direction of the arrows, andy Figure 3 is a;similar view taken at the cline 3-,3 on Fig. 1 and viewed in thedirection of the arrows. Figure 4 is an enlarged perspective view of aportion of the register construction of Fig. 1. Figure 5 is an enlargedsechighly tion taken at the line 5-1-5 on Fig. 3 andl viewed in thedirection of the arrows; and Figure 6, a broken perspective view-of aportion of one of the similar bars of which the structure is formed. I

lln the particular construction illustrated the register is formed ofaframe 7 shown as of general rectangularshape and made from four bars 8,9, 10 and 11, each of angle shape as represented in Fig. 2 to providethe depending portion 12 and the horizontallyextending portion 13, theends of the frame members referred to being preferably mi-` teredtogether at the corners of the frame, as for example by welding them.Located within the opening in the frame 7 is a series of bars 14 shownas extending parallel with each other and to the frame sides 9 and 1-1and spanning the Space from the members 7 to 10 these bars beingpreferably equidistantly spaced, and a second series of bars 15 shown asextending at' right angles to the bars 14 and into intersecting'relationtherewith, from theframe member 9 to the frame member 11. 'llhe bars '14are relatively wide as compared with the bars 15 as illustrated, eachalternate bar 14 containing a series of openings 16 preferably ofgeneral rectangular shape as shown, with oi'set portions represented at17 and `forming shoulders 18, the shoulders 18 being located at the sameside of each opening 16 as shown The other ones of the bars 14 aresimilarly recessed as represented at 19 withofset portions representedat 20 and forming 'shoul-p ders 21, these shoulders being located at thesame sides of the openings 19 but opposite to the sides at which theshoulders 18 are located. p rlhe openings 16 and 19 are shown as ofsuchsize as to permit the bars 15 -to be threaded therethrough, and f theshoulders 18 and '21.are so located that these shoulders will extendvinto alinement witlheach other in the finished structure, so that thebars 15 may, in strai ht condition,

lbe supported from'these shoul ers as shown.

The bars 15, which are. narrower than the bars 14, contain in theirupper surfaces notches 22 which are spaced apart the same distance thatthe bars 14 are spaced apart and are so proportioned that when the bars15 are positioned to seat on the shoulders 18 and 21, the upperportionsof the strips 14 at their recessed portionsextend into thenotches 22, whereby the upper surfaces of the bars 14 and 15 extend inthe same plane. The 'opposite ends of the v bars 14 and 15 are providedwith lugs represented at 23 and 24 respectively, these lugsbeinglocated'between the upper and lower edges ot the bars and extendingthrough slots 25 in the bars 8 and 10 and through similar slots (notshown) in the bars 9 and 11, respectively, their outer ends bein bentback against the outer surface of -t e frame to securely hold the bars14 and 15 in fixed position.

The parts of the grating are assembled by threading the rods 15 throughthefopenings 16 and 19 of the bars 14 and raising the bars -15 andshifting the bars 14 and 15 relative to each other in crosswisedirection, to cause the bars 15 to extend across the shoulders 18 and21, with the upper portions of the bars 14 extendin into the recesses22. After assembly of t e bars 14 and 15 as stated, the

bars extending through the openings in the frame members `provldedtherefor, and the lugs thereupon upset and the .frame memf Qtion, thebars of one series containing aperbers united together 'to form a solidtraineV structure.

llt Awill benoted that in the particular illustrated embodiment of myinvention the ybars 15, by reasonoi the arrangement of the shoulders 18and 21 at opposite sides of the openings 16 and 19, as hereinbeforeexplained, are held against accidental dispositioned inintersectingrelation and does not require any vfastening?"devices atthese points, the bars becominginterlocked in the o desired position by`merely adjusting them relative to each other" toseat the" kbars 15 'onthe shoulders 18 and 21". lf l. .i

lf desired the notches 22""may 'open downwardly instead y of upwardly.rin which case' the upper edges of the'bars'l would extend below theuppersurfacesv of the bars 14,' or,

if desired, in additionfto` the upper opening l notchesy 22vdownwardly'f opening notches (not shownj)finll vertical line therewithmay be rovided.'y u l hile llhaveillustrated describedv a particularVconstruction embodying my invention, I o notiwish'tobe understood asintending to limit it "thereto Ias the same may by Letters Patent, is
